Jeff Rowland Pre-Amps: The Corus & The Capri
Hi, the Corus replaced a treasured Synergy IIi. It provides more musical insight through lower noise level, extended bandwidth (an obviously deeper and cleaner bass) and fluidity (something highlighted by Roy Gregory in his recent HiFi+ review). U... 
Should i go Boulder 1060 or Jeff Rowland 625
I echo Thesoundhouse's comment: "Until there is away to audition your speakers with both those amps you are only guessing."It is hard to predict amplifier/speaker synergy - although you can eliminate testing some combinations by way of deduction. ... 
New Rowland Criterion 2-chassis battery pre
Here is very enthusiastic review of the Corus: http://hifi-unlimited.blogspot.com/2011/06/sensational-corus-jeff-rowland-corus.html 
New Rowland Criterion 2-chassis battery pre
The Corus and Criterion are essentially the same preamplifier design (compare internal pictures - their circuit boards are almost exactly the same) - so the gain range will be the same. My maximum volume range on the Corus is 60 to 65 - which is n... 
Jamming with JAMO?
I have the heard a friend’s Jamo R909 many times. They are one of the most impressive speakers I have ever heard. Their most significant strength compared to most planar and box loudspeakers is a very articulate and fast bass – in side by side com... 
Rowland 625
Thank you Guido for the detailed review - your impressions at various breakin times is interesting. 
Jeff Rowland Synergy IIi versus Capri and Corus?
Optimus - tough question since I don't have any experience with the 201. But I did have a similar dilemma because I was overall very happy with the Synergy IIi - so I was in fact considering an amplifier upgrade. I eventually decided that upgradin... 
Jeff Rowland Synergy IIi versus Capri and Corus?
I posted this elsewhere: As compared to the Synergy, the Corus is more transparent, quieter, images more precisely and has deeper cleaner bass.I really enjoyed the Synergy IIi which was I felt was very musical despite being fairly neutral. In retr... 
Rowland 625
There was a question re the Corus pre-amp. I have owned the Corus for two months following an upgrade from Synergy IIi.As compared to the Synergy, the Corus is more transparent, quieter, images more precisely and has deeper cleaner bass.I really e... 
Why are my B&W 803D speaks feel bright
I have used the 803D for the last 3 years - they are not by nature bright - in fact the aspect I most value is their relaxed fatigue free sound. I also use Audioquest cables, so they not the problem. So look to your other components. Also check yo... 
804Ds and bass performance
A few years ago I upgraded from 804S to 803D because I could not get the bass performance I was looking for from the 804S. I suspect, but cannot verify first hand, that while the 804D bass will be better than the 804S, they are still likely to be ... 
Has anyone upgraded Audioquest DBS from 36v to 72v
Yes, changed Jaguar interconnect battery pack from 36V to 72V, but didn't hear any obvious difference. 
Denon 3806 + B&W 803D....amp suggestions???
I currently own the 803D loudspeakers. I did not find that you necessarily need lots of Watts for the speakers to sound good. They need Amps (i.e. does the amplifier power double as the impedance halves) and quality (low noise, smoothness, transpa... 
New Rowland Criterion 2-chassis battery pre
Thank you Guido re the description of the volume control. The Synergy is similiar in that it also uses a optical encoder under microprocessor control. I am curious about what electronic circuit (whether chip or discrete) is used to implement the v... 
New Rowland Criterion 2-chassis battery pre
Hi Guido,Can you describe the volume control technology used for the Criterion?I currently own the Synergy IIi - the volume control design is based on the CS3310 IC. Rowland were careful in their design to maximise the performance from this now IC...
